Description
Technical Field
The present invention relates to a conveyor device for conveying a non-self-propelled movable body supporting a conveyed object along a travel rail.
Background
There are the following conveyor devices: a non-self-propelled movable body that supports a transported object is guided by a guide rail laid along a predetermined transport path, and the transport path includes a connected transport path section that transports a plurality of the movable bodies in a connected state and a separated transport path section that transports a plurality of the movable bodies in a separated state (see, for example, patent documents 1 and 2).
The conveyor device of patent document 1 includes a front coupling member and a rear coupling member at front and rear end portions of a movable body (carrier), a coupling device including a lifting rail and a hydraulic cylinder for lifting the lifting rail, and a separating device having the same configuration as the coupling device.
When the front and rear moving bodies are coupled, the front moving body is stopped in a state where the rear carriage of the front moving body is mounted on the elevating rail of the coupling device, and the front moving body is made to stand by in a state where the elevating rail is raised and the rear carriage of the front moving body is lifted. Then, the rear moving body is moved forward to stop the rear moving body in a state where the front coupling member of the rear moving body is moved below the rear coupling member of the front moving body, the lifting rail is lowered to bring the rear coupling member of the front moving body close to the front coupling member of the rear moving body, and the rear coupling member of the front moving body is coupled to the front coupling member of the rear moving body.
When separating the front and rear moving bodies, the front stage of the rear moving body of the front and rear moving bodies in a connected state is mounted on the position of the lifting rail of the separating device, the front and rear moving bodies are stopped, the lifting rail is lowered, and the front connecting member of the rear moving body is separated from the rear connecting member of the front moving body, thereby releasing the connection between the rear connecting member of the front moving body and the front connecting member of the rear moving body.
The conveyor device of patent document 2 includes a connected portion and a movable connecting tool at front and rear end portions of a moving body (a conveying carriage), and also includes a cam rail acting on a cam follower roller of the movable connecting tool as a connection start mechanism and a cam rail acting on the cam follower roller as a connection release mechanism.
Here, the coupled portion is constituted by a hook member having a hook-shaped tip portion facing upward.
The movable coupling device includes a pair of left and right arms extending rearward and movable up and down, an engagement portion formed by a horizontal shaft extending between rear end portions of the arms, and a cam follower roller or the like supported by the free end portion so as to extend laterally of the horizontal shaft, and is spring-biased at a lower limit coupling operation position.
Thus, the cam follower roller of the movable coupling tool is operated by the cam rail to move the engagement portion of the arm up and down, and the hook member of the coupled portion and the engagement portion (horizontal shaft) of the movable coupling tool can be switched between a coupling state in which the hook member and the engagement portion are engaged with each other and a state in which the coupling between the hook member and the engagement portion is released.

Disclosure of Invention
Problems to be solved by the invention
In the conveyor device of patent document 1, the coupling device and the separating device for coupling and separating the front and rear moving bodies are configured to include the lifting rail and the hydraulic cylinder as the lifting actuator for lifting and lowering the lifting rail, and a lifting guide mechanism for lifting and lowering the lifting rail and the lifting actuator are required, and therefore, the conveyor device has a complicated structure with a large number of components. This may increase the manufacturing cost and the maintenance cost, and may reduce the reliability of the operation.
In addition, since the front moving body and the rear moving body need to be stopped when the coupling device and the separating device are operated, the time required to stop the front moving body and the rear moving body becomes a loss that hinders the productivity.
In addition, in the conveyor device of patent document 2, it is necessary to provide a cam guide in addition to the guide rail, and it is necessary to provide a movable coupling device including a pair of left and right vertically movable arms, an engagement portion formed by a horizontal shaft extending between rear end portions of the arms, a cam follower roller, a spring, and the like, and thus a complicated structure with a large number of components is provided. This may increase the manufacturing cost and the maintenance cost, and may reduce the reliability of the operation.
In view of the above-described circumstances, an object of the present invention is to provide a conveyor device that can reduce manufacturing costs and maintenance costs and improve operational reliability by simplifying a structure for coupling and separating front and rear moving bodies adjacent to each other in a conveying direction.
Means for solving the problems
In order to solve the above-mentioned problems, the present invention provides a conveyor device in which a guide rail is laid along a predetermined conveyance path, and a non-self-propelled movable body that supports a conveyed object is guided and conveyed by the guide rail, wherein the conveyance path includes a connected conveyance path portion that conveys a plurality of the movable bodies in a connected state, and a separated conveyance path portion that conveys the plurality of the movable bodies in a separated state, wherein a non-movable front connection engagement portion and a non-movable rear connection engagement portion are provided at a front end and a rear end in a conveyance direction of the movable body, and the rear connection engagement portion of the front movable body and the front connection engagement portion of the rear movable body are brought into proximity or separated from each other in a vertical direction by bending the guide rail between a front movable body and a rear movable body adjacent to each other in the conveyance direction among the plurality of the movable bodies, thereby performing: a connecting operation of connecting the rear connecting engagement portion of the front moving body and the front connecting engagement portion of the rear moving body, among the front moving body and the rear moving body separated on the upstream side of the connecting and conveying path portion; and a separating operation of separating the rear coupling engagement portion of the front moving body from the front coupling engagement portion of the rear moving body, among the front moving body and the rear moving body coupled on the upstream side of the separation/conveyance path portion (claim 1).
According to this configuration, the front coupling engagement portion and the rear coupling engagement portion provided at the front end and the rear end of the moving body in the conveying direction are immovable, and the coupling operation and the decoupling operation of the front moving body and the rear moving body adjacent to each other in the conveying direction are performed by bending the guide rail in the vertical direction to bring the rear coupling engagement portion of the front moving body and the front coupling engagement portion of the rear moving body closer to or away from each other in the vertical direction.
This eliminates the need for an actuator or a movable coupling and engaging portion, and simplifies the structure for coupling and decoupling the front and rear moving bodies adjacent to each other in the conveying direction, thereby reducing the manufacturing cost and the maintenance cost and improving the reliability of the operation.
Here, it is preferable that the coupling operation and the separation operation are performed while the front moving body and the rear moving body are conveyed without stopping (claim 2).
According to this configuration, since the coupling operation and the separation operation of the front moving body and the rear moving body adjacent to each other in the conveying direction can be performed while the front moving body and the rear moving body are conveyed without stopping the front moving body and the rear moving body, it is possible to eliminate a loss of a stop time which hinders the improvement of the production efficiency.
Further, it is more preferable that the coupling operation is performed while the front moving body and the rear moving body are being conveyed in a state of being in contact with each other (claim 3).
According to this configuration, since the forward moving body and the backward moving body are brought into contact with each other and the connection operation is performed in a state where the conveying speeds are equal, it is not necessary to accurately match the conveying speeds of the forward moving body and the backward moving body, and therefore, the control is facilitated and the reliability of the connection operation is improved.
Further, it is more preferable that one of the front coupling engagement portion and the rear coupling engagement portion of the movable body is an engagement hole in a vertical direction, and the other is an engagement projection engaged with the engagement hole in the vertical direction (claim 4).
According to this configuration, the coupling operation and the separation operation of the front moving body and the rear moving body adjacent to each other in the conveying direction can be reliably performed with a simple structure, and the horizontal curved path can be also handled.
Further preferably, the movable body includes a drive surface against which the friction roller of the friction roller drive unit is pressed (claim 5).
According to this configuration, since the movable body has the driving surface against which the friction rollers are pressed, the speed can be easily changed and the noise is low, and the movable body can be conveyed by the friction roller type driving device which is a simple driving device relatively easy to install and modify.
More preferably, the movable body includes a structure in which a plurality of carriages provided with travel wheels that roll along the guide rails and disposed in front and rear in the transport direction are connected by a connecting rod having a main drive surface to which the friction roller is brought into pressure contact, a front carriage as a front end in the transport direction of the carriage is provided with a front extension rod that extends forward of a front vertical support shaft that connects a front end portion of the connecting rod to be horizontally swingable and has a sub drive surface, the front extension rod is horizontally swingable integrally with a main body of the front carriage with respect to the front vertical support shaft and is vertically swingable integrally with the connecting rod with respect to a horizontal support shaft of the front carriage, and a rear carriage as a rear end in the transport direction of the carriage is provided with a rear extension rod that is rearward of a rear vertical support shaft that connects a rear end portion of the connecting rod to be horizontally swingable and is provided with a rear support shaft And a sub-drive surface, wherein the rear extension rod is capable of swinging horizontally integrally with the main body of the rear carriage with respect to the rear vertical support shaft and is capable of swinging vertically integrally with the connecting rod with respect to the horizontal support shaft of the rear carriage (claim 6).
According to this structure, since the front extension bar and the rear extension bar are vertically swung integrally with the link, it is not necessary to provide relatively large clearances between the front extension bar and the link and between the rear extension bar and the link to avoid interference, as in the conventional carriage structure (for example, the carriage structure of japanese unexamined patent application publication No. 2003-300611) in which the front extension bar and the rear extension bar are vertically swung integrally with the main body of the carriage.
Accordingly, since the clearance between the primary drive surface and the secondary drive surface is small, even if the moving body is driven by pressing the friction roller from the primary drive surface to the secondary drive surface, the friction roller does not wear unevenly, and the reliability of the conveyor device including the friction roller type drive device is improved.
Effects of the invention
As described above, according to the conveyor device of the present invention, the structure for connecting and separating the front and rear moving bodies adjacent to each other in the conveying direction is mainly simplified, and therefore, the remarkable effects of reducing the manufacturing cost and the maintenance cost and improving the reliability of the operation are achieved.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the present specification, front, rear, left, and right are defined in a state of being directed to the transport direction of the moving body (for example, see arrow E in fig. 1 and 2), and a view viewed from the left is taken as a front view.
As shown in the schematic view of fig. 1, the front view of fig. 2, the longitudinal cross-sectional view of fig. 3 as viewed from the front, and the enlarged plan view of the main part of fig. 4 and 5, the conveyor device according to the embodiment of the present invention has a guide rail G laid along a predetermined conveyance path R, and guides and conveys a non-self-propelled movable body 1, … supporting a conveyed article by a conveyed article support 10 by the guide rail G. The conveyance path R includes a connected conveyance path unit R1 that conveys the plurality of moving bodies 1, … in a connected state, and a separated conveyance path unit R2 that conveys the plurality of moving bodies 1, … in a separated state.
The movable body 1 includes the following structure: the front truck 2 and the rear truck 3, which are provided with traveling wheels 7, … rolling along a guide rail G and are provided with horizontal guide rollers 8, … in the front and rear in the conveying direction E, are connected by a connecting rod 4.
Further, three or more carriages may be provided in front and rear of the conveying direction E, and the front and rear carriages adjacent to each other in the conveying direction E may be connected to each other by a plurality of links.
As shown in fig. 3, the moving body 1 is transported by bringing the friction roller 13 rotated by the gear motor M of the friction roller type driving device F into pressure contact with the driving surface D of the moving body 1 or by transmitting the driving force of the power chain type driving device or the like to the engagement stopper 9 of the front truck 2 and pulling it.
Since the moving body 1 includes the driving surface D, the speed can be easily changed and the noise is low, and the moving bodies 1, … can be conveyed by the friction roller type driving device F which is a simple driving device relatively easy to install and modify.
The movable body 1 includes a non-movable front coupling engagement portion C1 and a non-movable rear coupling engagement portion C2 at a front end E1 and a rear end E2.
Here, the front coupling engagement portion C1 is an engagement hole 11A formed in the vertical direction of the front protruding piece 11, and the rear coupling engagement portion C2 is an engagement projection 12A formed in the vertical direction of the rear protruding piece 12, but the front coupling engagement portion C1 may be an engagement projection in the vertical direction, and the rear coupling engagement portion C2 may be an engagement hole in the vertical direction.
By providing one of the front coupling engagement portion C1 and the rear coupling engagement portion C2 as a vertical engagement hole and the other as a vertical engagement projection, the coupling operation and the separation operation of the front and rear moving bodies, which will be described later, can be reliably performed with a simple structure, and the horizontal curved path shown in fig. 5 can be accommodated.
As shown in the enlarged plan view of the main portion of fig. 6A and the enlarged front view of the main portion of fig. 6B, and also in the enlarged plan view of the main portion of fig. 7A and the enlarged front view of the main portion of fig. 7B, the right and left side surfaces of the connecting rod 4 are the main driving surfaces D1 against which the friction rollers 13 are pressed.
The front truck 2 further includes a front extension bar 5, and the front extension bar 5 extends forward of a front vertical support shaft V1 that horizontally swingably connects a front end portion 4A of the connecting bar 4, and has a sub-driving surface D2.
The rear carriage 3 includes a rear extension lever 6, and the rear extension lever 6 extends rearward beyond a rear vertical support shaft V2 that horizontally swingably connects the rear end portion 4B of the connecting lever 4, and has a sub drive surface D3.
In the case where three or more carriages are provided in front and rear of the conveying direction E and the front and rear carriages adjacent to each other in the conveying direction E are connected by a plurality of connecting rods, the movable body 1 may be configured such that the front carriage as the foremost carriage in the conveying direction E of the three or more carriages is provided with the front extension rod 5 and the rear carriage as the rearmost carriage in the conveying direction E of the three or more carriages is provided with the rear extension rod 6.
Here, the front extension lever 5 is swingable horizontally integrally with the main body 2A of the front truck 2 with respect to the front vertical support shaft V1, and is swingable vertically integrally with the connecting lever 4 with respect to the horizontal support shaft H1 of the front truck 2. The rear extension lever 6 is swingable horizontally integrally with the main body 3A of the rear carriage 3 with respect to the rear vertical support shaft V2, and is swingable vertically integrally with the connecting lever 4 with respect to the horizontal support shaft H2 of the rear carriage 3.
In the case of conveying a moving body 1 ' of a conventional carriage structure (for example, a carriage structure of japanese patent application laid-open No. 2003-300611) shown in a front view of fig. 9 along a vertical curved path, since the front extension bar 5 ' and the rear extension bar 6 ' vertically swing integrally with the main bodies 2A ', 3A ' of the carriages 2 ', 3 ', it is necessary to provide relatively large gaps I, J between the front extension bar 5 ' and the link 4 and between the rear extension bar 6 ' and the link 4 to avoid interference.
On the other hand, when the moving body 1 having the carriage structure of the present invention shown in the front views of fig. 2 and 8 and also in the enlarged main part front views of fig. 6A to 6B and 7A to 7B is conveyed along the vertical curved path, the front extension bar 5 and the rear extension bar 6 vertically swing integrally with the link 4, and therefore, it is not necessary to provide a gap between the front extension bar 5 and the link 4 and between the rear extension bar 6 and the link 4 as in the conventional carriage structure described above to avoid interference.
Accordingly, since the clearance between the main drive surface D1 and the sub drive surfaces D2 and D3 shown in fig. 6B and 7B is small, even if the moving body 1 is driven by pressing the friction roller 13 from the main drive surface D1 to the sub drive surfaces D2 and D3, the friction roller 13 is not unevenly worn, and therefore, the reliability of the conveyor device including the friction roller drive device F is improved.
Next, a connection operation of connecting the rear coupling engagement portion C2 of the front moving body 1A and the front coupling engagement portion C1 of the rear moving body 1B, with front and rear moving bodies 1, 1 adjacent to each other in the conveyance direction E among the plurality of moving bodies 1, … being the front and rear moving bodies 1, 1A, 1B, will be described.
In the explanatory views of fig. 10A to 10B and fig. 11A to 11B, only the main body of the rear carriage 3 of the front moving body 1A and the main body of the front carriage 2 of the rear moving body 1B are shown together with the guide rail G shown by the two-dot chain line.
Here, the guide rail G includes a front high rear low inclination path portion a and a front low rear high inclination path portion B on the downstream side of the front high rear low inclination path portion a.
In the separating and conveying path portion R2 on the upstream side of the coupling and conveying path portion R1, the front moving body 1A and the rear moving body 1B are separated.
As shown in the explanatory diagram of fig. 10A, the forward moving body 1A and the backward moving body 1B are brought into contact with each other, and for example, the forward moving body 1A is pressed from behind by driving the backward moving body 1B, thereby being conveyed in the conveying direction E.
As shown in the explanatory diagram of fig. 10B, when the rear vehicle 3 of the front moving body 1A passes through the front-low rear-high inclined path portion B, the rear coupling engagement portion C2 descends together with the rear vehicle 3, and the front coupling engagement portion C1 of the rear moving body 1B is positioned above the rear coupling engagement portion C2.
Further, at the conveyance position in the explanatory view of fig. 11A, which is conveyed in the conveyance direction E, the front coupling engagement portion C1 is engaged with and coupled to the rear coupling engagement portion C2, and then, as shown in the explanatory view of fig. 11B, the state in which the front and rear moving bodies 1A, 1B are coupled is maintained.
Since the transport speeds of the front moving body 1A and the rear moving body 1B are made equal by transporting the front moving body 1A and the rear moving body 1B in a state of being in contact with each other as shown in fig. 10A, it is not necessary to accurately match the transport speeds of the front moving body 1A and the rear moving body 1B when performing the above-described coupling operation, so that control becomes easy and reliability of the coupling operation improves.
Next, a separating operation of separating the rear coupling engaging portion C2 of the front moving body 1A from the front coupling engaging portion C1 of the rear moving body 1B will be described.
In the explanatory views of fig. 12A to 12B and fig. 13A to 13B, only the main body of the rear carriage 3 of the front moving body 1A and the main body of the front carriage 2 of the rear moving body 1B are shown together with the guide rail G shown by the two-dot chain line.
Here, the guide rail G includes a front high rear low inclination path portion a and a front low rear high inclination path portion B on the downstream side of the front high rear low inclination path portion a.
The front moving body 1A and the rear moving body 1B are coupled to the coupled conveying path portion R1 on the upstream side of the separated conveying path portion R2.
When the vehicle is conveyed from the explanatory view of fig. 12A to the conveyance position of the explanatory view of fig. 13A via the explanatory view of fig. 12B, the rear carriage 3 of the front moving body 1A passes through the front low rear high inclined path portion B, the rear coupling engagement portion C2 descends together with the rear carriage 3, the engagement between the rear coupling engagement portion C2 and the front coupling engagement portion C1 is released, and the front moving body 1A and the rear moving body 1B are separated.
In this state, as shown in the explanatory view of fig. 13B, the preceding and following moving bodies 1A, 1B can be kept separated by rapidly conveying the preceding moving body 1A.
As described above, the coupling operation and the separating operation can be performed by bending the guide rail G in the vertical direction at an appropriate position of the conveying path R, for example, like the front high rear low inclined path portion a and the front low rear high inclined path portion B on the downstream side of the front high rear low inclined path portion a, and thereby making it possible to bring the rear coupling engagement portion C2 of the front moving body 1A and the front coupling engagement portion C1 of the rear moving body 1B closer to or away from each other in the vertical direction.
According to the conveyor device configured as described above, both the front end E1 and the rear end E2 of the moving bodies 1, … in the conveying direction E, which are provided with the front coupling engagement portion C1 and the rear coupling engagement portion C2, are of the immovable type, and the coupling operation and the separation operation of the front moving body 1A and the rear moving body 1B adjacent to each other in the conveying direction E are performed by bending the guide rail G in the vertical direction to bring the rear coupling engagement portion C2 of the front moving body 1A and the front coupling engagement portion C1 of the rear moving body 1B closer to or away from each other in the vertical direction.
This eliminates the need for an actuator or a movable coupling and engaging portion, and simplifies the structure for coupling and decoupling the front and rear moving bodies 1A and 1B adjacent to each other in the conveying direction E, thereby reducing the manufacturing cost and maintenance cost and improving the reliability of the operation.
Further, the coupling operation and the separation operation of the front moving body 1A and the rear moving body 1B adjacent to each other in the conveying direction E can be performed simultaneously with the conveyance without stopping the front moving body 1A and the rear moving body 1B, and the loss of the stop time which hinders the production efficiency can be eliminated.
In the above description, the example in which the conveyor device of the present invention is a floor-based conveyor has been described, but the conveyor device of the present invention may be an overhead conveyor.
